General properties and applications: The   products   are   a   blend   of   compressed   liquid   gases,   functioning   simultaneously   as propellant and active product.  They provide a jet of dry inert gas that acts like compressed air for a quick removal of dust particles and other dry contaminants from delicate or inaccessible areas of electrical and electronic equipment.  They help to eliminate failures caused by fluids (water, oil,..) trapped in dust or dirt.    The air dusters are essential for cleaning operations where liquid solvents are inappropriate.   The cleaning is quick and safe, harmless to plastics and other sensitive components.  They leave no residue or condensations.  Where possible, the dusters can replace the laborious and expensive compressed air cleaning.    The dusters can be used where it is difficult to remove dust using the conventional methods: electronic    equipment,    PCB’s,    cable    connections,    data   processing    &    communication equipment,   miniature   assemblies,   watch   mechanisms,   precision   instruments,   video   & cinema equipment, optics and lenses, … Specific properties and applications Dust Off 67 §  General purpose dust remover. §  Equipped with normal valve, button and extension tube.    §  Aerosol can only be used in upright position. §  Available 200 ml net (270 ml gross) and 400 ml net (520 ml gross). §  Has the DEKRA (*) certification. Dust Off 360 §  General purpose invertible duster. §  Equipped with normal valve, button and extension tube. §  Aerosol can be used in upright or upside-down position, not in horizontal position. §  Available 200 ml net (520 ml gross). §  Has the DEKRA (*) certification. Jet Clean 360 §  Invertible duster, designed for precise dust removal. §  Equipped with a special screw valve fitting.   §  A special nozzle for a precise flow is available as a separate item.    §  Aerosol can be used in upright or upside-down position, not in horizontal position. §  Available 200 ml net (520 ml gross). Dust Off HF §  High Flow dust remover, especially designed for heavy duty applications. §  Equipped with a valve and button combination, that allows a steady powerful blowing action. §  Delivered with extension tube for easy access of difficult to reach area’s. §  Aerosol can only be used in upright position.

Technical Data Sheet KONTAKT CHEMIE Duster Range Page 2/2 Technical data (**): Density @ 20°C Aerosol (liquefied gas) 1,01 g/cm³ Flame extension test   FEA 607 Negative (***) Drum test   FEA x 610 200 L Pass (> 60s) (***) Vapour pressure @ 20°C 420 kPa Flow rate Dust Off 67 Dust Off 360 Jet Clean 360 Dust Off HF ca 17 g/10s ca 17 g/10s ca 19 g/10s ca 67 g/10s General instructions: Spray the gas onto the objects and surfaces to be cleaned.  For best results, use the ‘quick shot’ method (spray in short blasts).  When the aerosol is cooling down and the pressure is decreasing (internal evaporation to restore the equilibrium in the aerosol can), wait a few moments for the internal pressure to restore and repeat the spraying action. Do not shake or move can during use. Specific instructions: Dust Off 67   Use the extension tube for hard to reach areas.    Spray in upright position (do not tilt more than 30°). Dust Off 360 Use the extension tube for hard to reach areas.    Spray in upright or upside down position (do not spray in horizontal position). Jet Clean 360 Screw on the precision nozzle (available as separate item).    Spray in upright or upside down position (do not spray in horizontal position). Dust Off HF Spray in upright position (do not tilt more than 30°). Use the extension tube for hard to reach areas.    Further information on safety can be found in the safety datasheet.
